Bridging the gap between BSE risk assessment and consumer perception of the surveillance system in Japan OAK
KADOHIRA, Mutsuyo; HILL, Glen; SAWADA, Manabu; YOSHIDA, Seiko; 門平, 睦代; ヒル, グレン; 澤田, 学; 吉田, 省子.
Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies...

SAWADA, Manabu; AIZAKI, Hideo; SATO, Kazuo; KIKKAWA, Toshiko; 澤田, 学; 合崎, 英男; 佐藤, 和夫; 吉川, 肇子.
The purpose of this paper was to verify the stability of consumers’ evaluations of food safety by conducting the identical choice experiments questionnaire survey at the same site two different times. The two surveys, measuring the consumers’ evaluations of beef derived from cattle fed in accordance with improved food safety measures were conducted in January 2003 (n = 83) and March 2004 (n = 369) in Kiyota ward of Sapporo city in Hokkaido, Japan. A comparison of the results of the two surveys suggests that social issues related to the choice experiment questions can significantly influence the consumers’ inferred values for food safety on the basis of the questions.本稿の目的は,同一の選択実験を同一地域の異なる2 時点で行い,食品安全性に関する消費者評価の安定性を 検討することである。北海道札幌市清田区の住民を対象...

冷凍枝豆の消費者選択 : 原産国と農場・加工会社形態の効果 OAK
葉, 雅雯; 澤田, 学; YEH, Yawen; SAWADA, Manabu.
小稿の目的は,国産冷凍枝豆と,原料枝豆農場と冷凍加工会社の形態が異なる複数の外国産冷凍枝豆が購入可能な状況を想定した冷凍枝豆の選択実験により,冷凍枝豆の原産国属性の消費者評価を計量的に明らかにすることである。北海道帯広市の215 名から得た選択実験回答データを条件付きロジットモデルで分析した結果,1)外国産冷凍枝豆に対する平均的消費者の支払意志額は,国産冷凍枝豆に比べ極めて低いが,「低価格志向」が強く,「国産志向」の弱い消費者では 国産と外国産の間の評価差が縮小する,2)原料枝豆栽培農場を日本の輸入販売会社の指定農場とすることで外国産冷凍枝豆に対する支払意志額が高まる,ことが明らかとなった。 The purpose of this study was to clarify quantitatively Japanese consumers’ valuation of frozen edamame. Two hundred and fifteen consumers living in Obihiro City, Hokkaido, served as respondents. Four different types of frozen edamame (domestic frozen edamame, frozen edamame from Taiwan, frozen edamame from Thailand, and frozen edamame from China) were analyzed in a choice experiment using a conditional logit model. The following results were obtained: 1)...

牛肉生産における飼料自給率向上の利点に関する消費者評価 OAK
澤田, 学; 合崎, 英男; 佐藤, 和夫; SAWADA, Manabu; AIZAKI, Hideo; SATO, Kazuo.
本稿の目的は,牛肉生産における飼料自給率向上の利点に関する消費者評価を検討することである。Best-Worst 選択質問実験を用いて牛肉生産における飼料自給率向上の利点に関する消費者の評価を測定する調査を,首都圏在住の618名を対象に2008年3月に実施した。分析の結果,回答者全体としては,「エサに対する安心感」が飼料自給率の向上で最も重視される項目であるが, 評価パターンによって回答者は3つの群に分けられることがわかった。さらに,評価パターンには,回答者の,倹約志向ならびに食の安全志向といった態度が顕著に影響することが確かめられた。The purpose of this paper was to verify consumers’ evaluations of the advantages of improving feed selfsufficiency in beef production. The survey, measuring consumers’ evaluations of the advantages of improving feed self-sufficiency in beef production using Best-Worst choice experiments, was conducted in March 2008 (n=618) in the Tokyo metropolitan area of Japan. The analysis of the survey data suggests that the respondents can be divided into three categories by the evaluation patterns, but...
